Lux is a unit of measurement for lighting used to determine the illuminance of a surface. It is a unit used in many different areas, such as in the design of lighting fixtures and in determining the illuminance of buildings. The term lux originates from the Latin language and literally means 'light'. Lux was first used in the mid-19th century by a French physicist known as the 'father of light measurement'. Since then, lux has been a widely used unit of measurement for lighting.

Lux - the definition

Lux is a unit of measurement for the amount of light falling on a surface. Lux is measured using a lux meter, which is a device that measures the amount of light falling on a surface. With the help of the lux meter, we can determine the illumination in a business space or building. In addition, the lux meter is also used to determine how much light is needed for a certain activity to function properly. An example of a situation in which lux is used is when determining the illuminance in buildings.

What is the difference between lux and Lumen?

Lux and lumen are two different units of measurement for lighting. Lux is a unit of measurement for the amount of light that falls on a surface, while Lumen is a unit of measurement for the amount of light that a light source emits. To calculate the illuminance on a surface, lux and Lumen are combined.

How many lux do I need in which room?

How many lux you need in a particular room depends on various factors. In some rooms you need more light than in others. For example, in a living room you need less light than in a work space. The required illuminance for a particular room also differs, this depends on the type of light you use. For example, the type of light and the color temperature you use in a work space should be different than in a living space. The ideal illuminance in a living space is approximately 300 lux. In a work space, the ideal illuminance is approximately 500 lux. In addition, it is also important to choose the right lighting fixtures to achieve the desired illuminance.

The guidelines for lighting in the workplace

The requirements for lighting in the workplace depend on various factors, such as the type of light you use and the illuminance. The required illuminance for lighting in the workplace is usually around 500 lux. The ideal color temperature is usually between 4000K and 5000K. This color temperature creates a bright light that is not too bright.

How is the lux number calculated?

The lux number is calculated using the following formula: Lux = lumen / (area x distance). In this formula, lumen is the amount of light emitted by a light source, area is the surface on which the light falls and distance is the distance between the light source and the surface. Using this formula, we can determine the illuminance on a surface by the amount of light emitted by the light source and the distance between the light source and the surface.
